 Description   

I'm using zabbix sender (via official python zabbix tools). Before 7.0, I sent a large text (stdout of Ansible with some extras) that includes newlines, and in the history widget I could see without issue.
After the upgrade to 7.0, the history widget doesn't show the newlines (it ignores them), at the text is like broken. Though if you go to "latest data" tab, you can see it correctly.

Same case happened while gathering data from Kubernetes API (http agent).

I tried using "as is" "html" and "monospace" font. Before 7.0 using "as is" worked well.{}

For now I'm using "single line", then click on the line to show a popup with the full text.
Example:

Let me add another example from Kubernetes. Using HTTP agent item type, then preprocessing jsonpath to get the text I need.
In the latest data you can see it perfectly formated. BTW, I think is not only newlines, but any special char

Which version of Zabbix frontend are you currently using? This issue seems very similar to one that was fixed in ZBX-24938 in version 7.0.5.

Is the "Use monospace font" option enabled in the configuration of this widget?

Comment by Leonardo Savoini [ 2024 Oct 28 ]

Last week I upgraded from 7.0.4 to 7.0.5, still the same.
Indeed, is the same issue.

Here is the widget. Confirmed, that are not only new lines, but tabs are missing too.

with "monospace" got the same results.

Debug:

Sorry, the newlines are good. What are missing are multiple spaces.

Just checked the JSON. There are no problem with special chars. Monospace doesn't seem to resolve the issue.

I confirm this issue. Thank you for the report! We will fix it.
